How do metals become stable?

Chemistry

Answer:

Atoms of metal elements give away electrons in their reactions to form positive ions. The ions formed have a full outer electron shell, so are very stable.

Explanation:

To become stable, the metal atom wants to get rid of one or more electrons in its outer shell. ... Alternately, an atom that loses electrons becomes a positively charged ion (aka cations). The particles in an ionic compound are held together because there are oppositely charged particles that are attracted to one another.

1. What causes wind? *

Gelneren [198K]

Answer:

it's the uneven heating of the region's of the troposphere by the sun the sun warms the air at the equator more than the air at the poles. it causes convention currents large scale patterns of winds that move heat and moisture around the globe. as air rises expands and cools water vapor condenses and clouds develop.

When two fluorine atoms bond together in F2, what type of covalent bond do they form?

makvit [3.9K]

When two fluorine atoms bond together in f2 the type of covalent bond do they form is non-polar covalent bond.

Explanation

They are two type of covalent bond. that is non polar covalent bond and polar covalent bond.

Non polar covalent bond is formed when atoms share a pair of electrons with each other equally.

polar covalent bond is bond formed when atoms share a pair electrons unequally.

F2 is a non polar since it is made up of two same atoms which has the same electronegativity, therefore equal number of electrons exist in the orbital overlap.

Calculate the Ka of your acetic acid solution. Discuss this calculation. Based on the value of Ka, is acetic acid a strong acid

lord [1]

Based on our knowledge of strong and weak acids, we can confirm that the Ka value for acetic acid will be relatively low since it is a weak acid.

Acids can be strong or weak. This is determined by its tendency to break apart into ions or stay together to form molecules. Although somewhat counter-intuitive, strong acids are those that are most likely to break apart and therefore contain a high number of ions within their solutions.

Weak acids, on the other hand, are those that tend to stay together in the form of molecules and therefore possess very low ion counts in their solutions. The acid dissociation constant, Kₐ, is used to measure whether an acid is weak or strong and how much so. In the case of Acetic acid, the ka measurement will offer a low value, indicating a weak acid.
